Initial commit: POE2 automated trade bot

Monitors pathofexile.com/trade2 for new listings, travels to seller
hideouts, buys items from public stash tabs, and stores them.

Includes persistent C# OCR daemon for fast screen capture + Windows
native OCR, web dashboard for managing trade links and settings,
and full game automation via Win32 SendInput.
